Ask questions and find answers on ST25 NFC/RFID tags and readers, including connectivity implementations and antenna design.
Hi For a school project we are working with the ST25R3916 to read/write MIFARE CLASSIC cards, but I'm stuck on the reading part. I found this in de datasheet: "Low level modes to implementMIFARE Classic® compliant or other custom protocols", What mod...
Hello,Looking to integrate the ST25 in an ultra space constrained environment. As such antenna space is very limited so it seems like the best solution would be a wire wound inductor as read distance is not supercritical. The Pulse W3102 4.7uH induct...
X_NUCLEO_NFC05A1 please send me how to kernel driver file and device tree configuration and make menu configuration on this device if any supported links are there means please share us it is very helpful and also what are the changes i want to do fo...
Our app is based on a cross platform framework that uses phone-gap. we understand you provide some st nfc libraries that does this, but we would like to know the actual android/ios api used for this. please help.
I am developing an application that works with energy harvesting (EH).In doing so, I examined the EH function more closely and found strange behavior.What I have done:hardware: - IC used: ST25DV04K-IER6S3 - design of three custom tags (similar to som...
Hi,I have some trouble with reading of 2 cards. Sometimes I will get the result code 0x90 from CR95HF.Why this occours? What are the reasons for this? What should I do to improve the funtionality?I have a custom board with the antenna design of the C...
Hello ST and users In the ST25RU3993 EVAL boared, the micro controller interacts with the RFID reader chip through SPI interface and control signals ( 93_signals) - altogether six data lines in total. The SPI interface is also shared with a carrier c...
